Don't go into this one expecting a romance. I'm not sure why, but I fully believed this book was about a DNA test match-making thing geared toward young adult audiences. It's not.

DNA testing plays a role, but instead of a boyfriend, Abby walks away with a full-blood sister she had no clue existed. Soon, she finds that Savvy (her instagram-star blood-sister) reached out to her and wants to meet up.

Eventually, they're at this summer camp together, where they try to figure out how in the actual hell this happened.

Don't get me wrong, there is a sprinkle of romance, which didn't come off as believable to me. Abby and her best-guy-friend Leo have been making eyes at each other since their childhood and it surfaces while at camp. It's an awkward kind of romance that didn't feel genuine.

However, the main plot is great. Twisty and full of drama.
